I have defined a service called "nrm" at TCP port 8009. One of my
Linux servers keeps having that service added back to it, even
though I know this service shouldn't be running on that server. I
have deleted the IpService from the device, even selected Lock from
Update and Deletions - but it still reappears every couple of hours.
It then generates an Event saying that this service is Down!
How can I prevent this from happening?
Zenoss discovers the listening TCP ports using SNMP. However, it
monitors these ports by trying to connect to them. This means that it
can find ports that are listening, but firewalled from the Zenoss
server. I'd login to the server and run a "netstat -an|grep 8009" to
make sure that the port is not listening. I've never seen a condition
where the SNMP agent reports a port as listening if it really isn't.
If you don't want to monitor a port, click into it from the device's
OS tab and change the monitor property to False instead of deleting
the IpService.
